Abstract Flowering is a major developmental transition in plants, but asynchronous flowering hinders the utilization of wild cotton relatives breeding programs. We performed comparative transcriptomic profiling early‐ and late‐flowering Gossypium hirsutum genotypes to elucidate genetic factors influencing reproductive timing. Shoot apices were sampled from photoperiod‐sensitive landrace G. purpurascens ( GhP ) early‐maturing variety ZhongMianSuo (ZMS) at five time points following emergence sympodial nodes. RNA‐sequencing revealed extensive transcriptional differences during floral transition. Numerous flowering‐associated genes exhibited genotype‐specific expression, including FLOWERING LOCUS T FT homologs upregulated ZMS. FT‐interacting like SOC1 CO ‐like also showed higher expression ZMS, implicating florigen pathways early flowering. Additionally, circadian clock light signalling components misregulated between varieties, suggesting altered photoperiod responses GhP. Weighted co‐expression network analysis specifically linked module enriched for circadian‐related GhP's late Through an integrated transcriptome analysis, we defined regulatory landscape phase change cotton. Differentially expressed related photoperiod, clock, likely contribute delayed cottons. Characterization upstream regulators will enable modifying sensitivity expand germplasm use improvement. This study provides candidate targets elucidating interactive mechanisms that control across diverse genotypes.

Leaf color mutants serve as ideal materials for studying photosynthesis, chlorophyll metabolism, and other physiological processes. Here, we identified a spontaneous yellow-leaf mutant (yl1) with chlorophyll-reduced leaves from G. hirsutum L. cv ZM24. Compare to wild type ZM24 green leaves, yl1 exhibited patchy yellow reduced content. To further explore the mechanisms of phenotype plant, transcriptomics proteomics profiles were conducted types. A total 9247 differentially expressed genes (DEGs) 1368 accumulated proteins (DAPs) identified. Following gene ontology (GO) annotation KEGG enrichment, DEGs/DAPs found be significantly involved in multiple important pathways, including obsolete oxidation-reduction process, light-harvesting, microtubule-based cell redox homeostasis, carbohydrate metabolic process. In photosynthesis light-harvesting pathway, 39 DAPs/DEGs identified, 9 PSI, 7 PS II, protein complex (LHC), 10 PsbP family, 4 cytochrome b6/f complex. validate reliability omics data, GhPPD1, DAPs was knocked down cotton using TRV-based VIGS system, it observed that GhPPD1-silenced plants color, accompanied by significant decrease conclusion, this study integrated transcriptomic proteomic approaches gain deeper understanding underlying leaf phenotype.

Frontiers in Bioengineering and Biotechnology, Год журнала: 2024, Номер 12

Опубликована: Авг. 29, 2024

This review article delves into the vital aspects of cotton, emphasizing its global significance as a crucial agricultural commodity. The paper comprehensively explores composition cotton and surveys diverse methods employed for removal lint from seeds. Conventional delinting methods, including mechanical chemical approaches, are scrutinized in terms their advantages drawbacks. However, primary focus this is on highlighting emerging biological methods. By harnessing power microbial enzymes organisms, approaches offer promising alternative efficient removal. authors discuss environmental associated with delinting, positioning it sustainable solution that mitigates ecological impact traditional Furthermore, contextualizes these within framework Sustainable Development Goals (SDGs) underscores importance adopting eco-friendly practices industry to align SDG goals. accentuating potential contributing agriculture responsible production, advocates paradigm shift towards more environmentally conscious sector. Overall, aims provide comprehensive perspective pivotal role alternatives fostering goal-oriented future industry.
